Abstract: A fiber and a process for obtaining same from a high-modulus polyethylene, extrudable in state-of-the-art equipment and in the absence of previous solubilization in any kind of organic solvent is described, the process comprising providing such a polyethylene, introducing it in a state-of-the-art extruder, extruding it according to a temperature pattern, obtaining an extrudate that is directed to a cooling bath to have its temperature reduced, then directing the extrudate to a first stretcher where it is stretched or drawn into a fiber of improved tenacity, at a first velocity v1, then heating the fiber at nearly 90° C. and then directing said fiber to a second stretcher to be drawn at a final velocity v2, wherein v1<v2, at a draw ratio of 2/1 until 65/1. The tenacity of the polyethylene fiber obtained by the said process attains at least 4 gf/den, which makes it useful to naval and offshore applications.

Abstract: A self-clearing grilling fork is provided wherein the a reciprocating clearing plate associated with tines of a grilling fork. This reciprocating clearing plate is activated by a spring loaded trigger mechanism in the pistol grip handle of the fork. The displacement of the trigger causes a rod, within the hollow tubular shaft of the fork, causes linear movement of the clearing plate relative to the tines on the end of the fork and thus displaces food and food residues from the tines on the end of the fork. In the preferred embodiments of this grilling fork a seal is provided within the hollow tubular shaft of the grilling fork to both facilitate relative movement of the rod with this shaft, and to otherwise seal the opening in the shaft to prevent food and debris associated with the cooking environment for entering into the shaft.
